vbulletin search (the version we have installed here) doesn't take advantage of "and" / "or" / "xor" / "not" as boolean operators inside a search term, it rather interpretes these words as simple search keywords and this way it excludes them from the search cause they are "too common" (they wouldn't bring a more concrete result, quite the contrary). also the symbolic boolean operators "&" / "|" / "^" / "!" don't work here.
instead, you can use:
"+" to assign that a keyword must be part in each result set
example "+alexandra +nice" returns results having both words in.
"-" to assign that the keyword is not part of the result
example "alexandra -nice" returns all results for alexandra without those having "nice" included.
afaik you can combine as much words as you like, with both operators. and also, i think that the "+" operator is the default operator for any searchword you add to your term. that you get huge resultsets in return is rather based on searches you fire on all posts (default search) instead of limiting the search to thread titles (or other limit-options in the advanced search form).
if you want to use boolean operators for a specific search, this is a good hint:

with google search you have much more control to receive an expected result but i wouldn't be sure that it delivers each result possible.
